根据研究对象不同,制冷系统稳定性可分为蒸发器完全蒸干点随机振荡现象研究、蒸发器和热力膨胀阀控制回路稳定性研究和定容量制冷系统稳定性研究三个阶段。对变排量压缩机汽车空调制冷系统的稳定性问题进行了初步分析,指出该系统中两个流量调节装置存在相互之间的参数耦合和调节协调问题。根据系统使用情况及其非线性的特点,可将变排量压缩机汽车空调制冷系统稳定性划分为小扰动稳定性和大扰动稳定性。
According to the different objects of study, the stability of refrigeration system can be divided into evaporator evaporation point completely random phenomenon, evaporator and thermal expansion valve control loop stability and stability of the constant capacity refrigeration system in three stages. The stability of variable displacement compressor automobile air conditioning and refrigeration system is analyzed preliminarily. It is pointed out that the two flow regulating devices in the system have the problems of parameter coupling and coordination between each other. According to the use of the system and its nonlinear characteristics, the stability of variable displacement compressor automotive air conditioning and refrigeration system can be divided into small disturbance stability and large disturbance stability.
